Turkey Vulture (also known as Turkey Buzzard, John Crow, or Carrion Crow)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Cathartes, Species: aura
Family: Cathartidae (New World Vultures)
- Shape
- Highly asymmetrical outer vanes on primaries with distinct emargination (notching) on the leading edge to reduce drag and increase lift during soaring. The overall shape is elongated with a slightly rounded tip.
- Size
- Estimated between 12 to 16 inches (30–40 cm) in length. This is consistent with the large wingspan of a Turkey Vulture, where primaries typically reach this significant size.
- Rarity
- Very Common. One of the most widespread and frequently observed large birds in North America.

Description
These feathers belong to a large soaring bird with a wingspan of 63–72 inches. The Turkey Vulture is easily identified in flight by its 'V' shaped dihedral wing position and its red, featherless head. Its plumage is almost entirely brownish-black, contrasting with the silver-gray undersides of its flight feathers.
Colour & Pattern
Uniform dark brownish-black to charcoal gray on the dorsal surface. The ventral side (underside) would appear more silvery-gray. There are no bars or spots, which is a key diagnostic feature for this species.
Barb Structure
Densely packed pennisanceous barbs that are tightly interlocked except at the base; the barbs are stiff and resilient to withstand the air pressure of soaring flight. Minor fraying is visible on the trailing edges.
Texture & Surface
Matte finish with a slightly coarse, stiff texture. Unlike waterbirds, they lack an oily coating but are designed for extreme aerodynamic durability.
Key Features
Large size, uniform dark coloration without banding, and a distinctively pale/white thick rachis at the base.
Habitat
Extremely versatile: found in open country, subtropical forests, shrublands, deserts, and even urban areas where carrion is available. They prefer areas with thermals for soaring.
Geographic Range
Widespread throughout the Americas, from southern Canada to the southernmost tip of South America. Northern populations are migratory, wintering in the southern US and further south.
Ecological Role
Nature's cleanup crew. As obligate scavengers, they prevent the spread of diseases (such as anthrax and rabies) by efficiently removing carrion from the environment.
Similar Species
Black Vulture (shorter, wider feathers with more white at the tips), Golden Eagle (usually shows some faint banding or mottling and darker rachis), and California Condor (significantly larger and much rarer).
Interesting Facts
Turkey Vultures are one of the few birds with a highly developed sense of smell, allowing them to locate carcasses hidden under forest canopies. They also practice urohidrosis—defecating on their legs to cool down via evaporation.
Condition Notes
Good condition. There is some minor 'zip' loss in the barbs (slight splitting) and some accumulated dust/debris, but the integrity of the vanes remains high.
